more ios certificate issues

Hello,

I really enjoy publishing Adobe Air stuff on the Android market but when it comes to IOS and the Appstore I get the camps.

I am a freelance game developer and I made few games for a major TV channel.

Publish them on the android market was easy pizy.

The problems came when I tried uploading them to Apple's appstiore.

I believe that the main problem is that I work on a PC and not Mac.

I got a .P12 file and a  password from the company but I couldn't publish it on my Flash Professional CS5.5.

(it was not a password but something to do with the key)

than I got another P12, which was accepted and published to an ipa by  my Flash Professional CS5.5 but when I uploaded it

to the appstore using a Mac I got the error msg showing in the image below

Any ideas, thought,   links to ease my sufferings

(i know how to develop games... much less about certificates and provisions)
